Senior Structures Engineer, Lunar

Vast is developing next-generation space stations and space infrastructure using an incremental, hardware-rich, and low-cost approach. Vast is rapidly developing its multi-module Haven Station to ensure a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and unlocking a new space economy for government, corporate, and private customers. Haven Demo’s 2025 success made Vast the only operational commercial space station company to fly and operate its own spacecraft. Next, Haven-1 is expected to become the world’s first commercial space station when it launches in 2027, followed by additional Haven modules. Additionally, the company recently announced Vast Satellite, a high-power satellite product line leveraging its space station components and the heritage of Haven Demo.

Headquartered in Long Beach, California, and with more than 1,000 employees and over a billion dollars in private capital, Vast has built the facilities required to manufacture and operate America’s next space station. The company plans to develop future habitats and systems for the Moon and Mars, dedicated space stations for government partners, and other crewed systems that will unlock the expanding long-term space economy.

Vast is looking for a Senior Structures Engineer, Lunar, reporting to the Senior Vice President, Lunar Programs, to support the development of the systems that will be required for Vast’s Lunar ecosystem. Our team is applying the technology, infrastructure, and knowledge built across our Haven Demo, Haven-1, Haven Station, and Vast Satellite programs to a new frontier: the Moon. Our Lunar program isn't starting from scratch, giving this founding team an extraordinary running start to help shape humanity's next era of lunar exploration from day one.

As  one of the earliest Structures Engineers on the Lunar team, you'll play an outsized part in developing Vast’s lunar ecosystem. In this role you will have the opportunity to cover a wide range of components and systems for the Moon ranging from the primary pressure hull and lunar surface habitat structures, secondary structures and closeouts and mechanisms, to micrometeoroid shielding.  You will concept, design, build, and test engineered systems that require an understanding of mechanical design, structural safety factors, welding processes, and materials engineering.  The ideal candidate will be a full-ownership responsible engineer with broad knowledge that can take a product from beginning to end. 

This will be a full-time, exempt position located in our Long Beach location. 

Responsibilities: 

• Serve as the accountable owner (Responsible Engineer) for end-to-end lunar engineering projects such as habitation modules, airlocks, nodes, and pallets.
• Work with lunar subject matter experts and systems architects to bring lunar concepts to reality that mesh with Vast’s larger lunar ecosystem and NASA’s Moon Base architecture. 
• Own the design and CAD (NX or equivalent) development of primary and secondary structures for lunar ecosystem.
• Develop understanding of static and dynamic loads, vibrations, thermal, and other environmental considerations unique to the lunar surface to drive design decisions.
• Define structural requirements, design loads, and safety margins for a human-rated pressurized structure operating in the lunar environment.
• Perform mechanical design and analysis, develop manufacturing drawings, following hardware through the entire process from concept to build.
• Lead trades and own interfaces with subsystems, including pressure vessel architecture, hatch/seal mechanisms, and material selection for lunar exposure conditions.
• Work with fabricators and technicians to improve designs, develop processes, and resolve issues.
• Define and execute test and verification plans, including structural, pressure, and hatch/seal performance testing.
• Support hardware bring-up, checkout, and anomaly resolution during build and test.
• Represent the subsystem at design reviews, coordinating with Life Support (ECLSS), Thermal, Power, and Avionics teams  on interface requirements.
• Help establish design standards and practices for the Lunar program as its first structures hire.

Minimum Qualifications:

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Civil Engineering, Physics, Mathematics  or a related field.
• 5+ years of experience in structural design of aerospace pressurized or human-rated hardware, with direct ownership from design through hardware delivery.
• 5+ years of experience with CAD and FEA software packages (NX or equivalent) and experience with GD&T implementation and analysis (ASME Y14.5).
• Demonstrated experience owning a structural hardware item end-to-end (design, build, and test), not solely in an analysis capacity.

Preferred Skills & Experience:

• Experience working on lunar engineering programs.
• Design of structures and components for a high-performance vehicle or spacecraft.
• Experience designing pressure vessels, hatches, or airlock mechanisms for crewed spacecraft or habitats.
• Familiarity with spacecraft structural specifications such as SMC-S-016 and NASA-STD-5001.
• Analysis work in recent versions of Ansys, Femap/Nastran, or Abaqus.
• Experience leading hardware through structural verification testing (proof pressure, burst, functional seal/hatch cycling).
• Familiarity with the lunar surface or deep-space thermal, radiation, and solar environment (or equivalent extreme-environment design experience).
• Prior experience in a fast-paced commercial space or startup hardware environment, comfortable with high ownership and limited process overhead.

Additional Requirements:

• Ability to travel up to 5% of the time to support vendors, partnership or customer meetings.
• Willingness to work evenings and/or weekends to support critical mission milestones.

Pay Range: California$137,000—$230,000 USD

We calibrate level and compensation to the selected candidate's experience and demonstrated capability. We welcome applicants across a range of experience levels to apply.

COMPENSATION AND BENEFITS

Base salary will vary depending on job-related knowledge, education, skills, experience, business needs, and market demand. Salary is just one component of our comprehensive compensation package. Full-time employees also receive company equity, as well as access to a full suite of compelling benefits and perks, including: medical, dental, and vision coverage for employees and dependents, generous paid time off; up to 20+ days of vacation for exempt staff and up to 10+ days of vacation for non-exempt staff with the ability to cash-out unused vacation annually, paid parental leave, short and long-term disability insurance, life insurance, access to a 401(k) retirement plan, ClassPass credits, personalized mental healthcare through Spring Health, and other discounts and perks.
